| Abstract: | This paper expounds in detail the process of mapping by digital scanning. It can be divided into the following steps: turning the original map to the style of grid of digital map, by data handling and map compiling, which turns the format of lattice of digital map to the format of vector. And then the author tries to originate an applicable method about the digital mapping.The precision and error are analyzed in this process, making it more reliable. |

| Keywords: | terrain map scanning digitalization format of lattice digital map format of vector digital map |
